MEANS FOR DESTROYING ANIMALS.

SPECIFICATION forming part of Letters Patent No. 768,620, dated August 30, 1904. Application filed December 8, 1903. Serial No- 184,346. (No model.)

T0 on whom it may concern:

Be it known that I, BENJAMIN PARKER, a subject of the King of Great Britain, residing at Coimadai, in' the State of Victoria, Australia, have invented a new and useful Means for Destroying Animals, of which the following is a specification.

This invention has been devised to provide a means for destroying undesirable animals, such as rabbits, foxes, and like vermin. I employ a flat plate set on the end of a lever. Said lever at the opposite end opens into the valve of a cylinder containing compressed air or gas and allows a squirt to escape through asmall nozzle placed slightly above the ground and pointed toward said plate. Poisoned liquid is contained in an adjacent cylinder, and the air escapingcauses a small quantity to be squirted out therewith when the plate is depressed by the weight of the rabbit passing The plate is placed in the track, preferably near the mouth of the burrow, and the whole arranged so that the liquid squirts from the nozzle onto the body of the animal, who endeavors to remove such liquid by licking the part, and thus becomes poisoned and dies.

In the accompanying drawings, Figure l is a side view of the apparatus; Fig. 2, a plan of same; Fig. 3, a vertical longitudinal section taken at one end of the apparatus, and Fig. 4: a similar section showing other parts.

A represents a cylinder or reservoir that contains poisoned liquid, and B a pipe-elbow that enters the cylinder andcarries a valve B, such as that used in connection with the pneumatic tires of bicycles. By means of this valve and a hand-pump air canv be supplied under pressure into the space above the liquid in the cylinder. Attached to the end of this cylinder also is piping D, havingconnected passage-ways D D D D. ries a tube O, bent and directed toward the opposite end of the cylinder and terminating as a squirt-nozzle; Communication is formed between the cylinder A and D by small pipe E. The passage-way D forms a chamber for a valve H and contains a spiral spring F beneath same and is closed by a cap. Gr. The valve is supported by valve-rod H, thatpasses through The piping carthe passage-way D The valveis actuated by pressure upon the valve-rod. The piping D has hinged to it a block J, that is connected by an arm J to plate J block J that bears upon a flat spring K. The valve-rod projects into a recess in the block J and is actuated by a downward presure of this block when a weight is on the plate J The machine is placed with the plate J set ina horizontal position at the ground-level beside a burrow of the rabbits or other suitable place. The rabbits as they pass over and tread upon the plate J 2 will depress same, so that the hinged block J will act upon the rod H to open the valve D and the air-pressure within the cylinder will cause the liquid to be forced upthrough the pipe E and passages D D D and D and out by the pipe (1. The pipe 0 is directed toward the plate J so that immediately the pressure is put upon such plate a squirt or spray of the liquid will be forced out by the tubes E onto the rabbit. The rabbit thus receives the spray of poisoned liquid and, it has been found, will be poisoned by licking the same from its coat. In lieu of air I reserve to myself the use of any other suitable gas under pressure to expel the poisoned liquid. I

I would have it clearly understood that I do not confine myself rigidly to placing the plate or plates at the mouth of the burrow, as I may in some cases place them in a newlycut furrow or a like convenient position.

The liquid will preferably contain a solution of arsenic, strychnine, or other poisonous or corrosive matter of sufiicient strength to kill the animal.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is I 1. Means for destroying rabbits consisting of a chamber containing poisonous liquid and a tube therefrom with nozzle directed toward the chamber and means whereby the rabbit or animal by its weight will cause liquid to squirt from the chamber onto itself.

2. In combination, a reservoir to contain poisoned liquid, means for supplying air under pressure to the reservoir, a squirt-tube connected with the reservoir, a valve connected Beneath the arm J 2 is a I with the sqnirttul e and a foot-plate arranged l arranged to operate the valve on pressure l eto operate the valve on pressure heingapplied l mg applied to it substantially as and for the to it substantially as and for the purposes (10- purposes described.
